INSULATED RAIL-JOINT.

SPECIFICATION forming part of Letters Patent No. 765,370, dated July 19,1904. Application iiled December 28, 1903. Serial No. 186,837. (Nomodel.)

To a/ZZ whom it may concern:

Be it known that I, GEORGE A. WEBER, a citizen of the United States, anda resident of the borough of Manhattan, city, county, and State of NewYork, have invented certain `new and useful Improvements in InsulatedRail- Joints, of which the following is a specification accompanied bydrawings.

This invention relates to insulated railjoints; and its objects are tosecure eiicient insulating means for insulating girder-joints, while atthe same time affording the requisite strength and efliciency for thejoint.

Another object of the invention is to prevent the rails from wearingthrough the insulation beneath their bases and establishing a shortcircuit.

Further objects of the invention will hereinafter appear; and to theseends the invention consists of an insulated rail-joint embodying thefeatures of construction.combinations of elements, and arrangement ofparts, substantially as hereinafter fully described and claimed in thisspecification, and shown in the accompanying drawings, in which- Figures1 and 2 are transverse sectional views of joints embodying theinvention.Eig.

3 is aplan view. Fig. 4 is a side elevation of Fig. 1. Fig. 5 is asectional view vof a chair, insulating material, and protective plates.Fig. 6 is a perspective View of the chair, insulating material, andprotective plates. Fig. 7 is a side elevation of the chair.v

Referring to the drawings, A and B represent the meeting ends of rails,in this instance shown as girder-rails having a high web portion C. Therails rest upon the chair D, having a base E, upright F, with a spikingrib or fillet G. Any suitable rail-chair may be used, the oneillustrated being shown of suitable and usual construction. yAlong thewebs of the rails are arranged the filling-blocks H, which may be ofwood and sectional or continuous, as desired.

Opposite the upright E of the chair, which forms a bolt-plate, arearranged metallic bars or straps I, extending across the joint. In

Fig. 2 one bar or strap J is shown extending piece lH.

across the joint. In both figures the plurality of rows of bolts K areshown securing the parts of the joint together. In Fig. l the upper rowof bolts passes through the upper strap I and thelower row passesthrough the lower strap. In Fig. 2 both rows of bolts pass through thesingle strap J. Any desired nurnber of rows of bolts may be used, inthis instance two being shown by way of illustration.

The rrails are insulated from the base of the chair by suitableinsulation L, which may be secured in position in any suitable manner.In Fig. l it is shown extending between the upright of the chair and thefilling-block H at that side of the joint, While in Fig. 2 it is shownat the other side of the joint extending up between the strap or bar .Iand thefilling- In either case the material is clamped between the partsof the joint and held in position. The bolts are suitably insulated fromthechair and from the bars I or J by the usual insulating-sleeves O andwashers P. The tendency of the rails is to wear into theinsulation L,and in order to prevent this as much as possible it has been foundadvantageous and convenient to place metallic protective plates Qbetween the bases of the rails and the insulation L, as shown moreparticularly in Figs. 6, 7, and 8. These plates Q do not extendcontinuously across the joint,

as shown, a spacel being left at the meeting ends of therails to preventcurrent from passing from one rail to the other through the plates. Theplates Q may be thin and have been found to operate advantageously forcarrying out the objects for which they are designed.

The plates Q may of course be used with any form of insulated joint towhich they are applicable, and the method of securing the insulation L,as shown in F ig. 2, may be applied to any form of insulated joint towhich it is applicable.

Obviously some features of this invention may be used without others,and the invention may be embodied in widely-varying forms.

Therefore without limiting the invention tion on the base of the chair.metallic protective means for the same between the insulation and thebases of the rails, rail ends to be insulated one from the other, andinsulating means for maintaining said rails in alinement, forsubstantially the purposes set forth.

In testimony whereofl I have signed this specification in the presenceof two subscribing witnesses.
